Hello, thanks for the video. One of my car had CEL code for “too lean”
condition, OBD2 scanner found really high LTFT (15%). I troubled shoot and
found out it was caused by a bad O2 sensor. Replaced it and fixed the
problem. I have another car (2001 BMW 330I at 160K mileage). LTFT and
STFT of both banks are ~ 0%. My question is that if 0% LTFT is a clear
indication of good O2 sensor? Thanks much.
Thanks. Good read

Those terminals are bent now by front probing them. That’s what you don’t
do…

You shouldn’t measure the heating voltage against the engine ground but
against the heating ground wire, because that’s where the sensor heater
also gets it’s ground. So measure between terminals 1 and 3.
Thanks. Good read
a d v o m…..not a doom!!! fucking spell check!
you cannot look at a ground and tell if its good.
Good info for future thanks
